FREDERICK JEFFERSON, OF WEST BROMVVICH, ENGLAND.

CARBON-SHEET HOLDER.

SPECIFICATION forming part of Letters Patent No. 763,762, dated June 28,1904. Application filed October 12, 1903- Serial No. 176,792. (Nomodel.)

1'0 all whom, it may concern.-

Be it known that I, FREpERroK JEFFERSON, a subject of the King of GreatBritain, residing at High street, West Bromwich, England, have inventeda certain new or Improved (Jarbon-Sheet Holder, of which the followingis a specification.

My invention consists of the new or improved combined support-ing plateor board and carbonicpaper carrier hereinafter described to be used inmanifold writing, the said invention having for its principal objects torender unnecessary the handling of the carbonic paper and to obviate theattendant objection theretonamely, the soiling of the fingerstofacilitate the introduction of the carbonic paper between the pages ofthe manifold-copy book, and to permit of the simultaneous withdrawal ofthe writing plate or board and carbonic paper.

By the expression carbonic paper I wish it to be understood that Iinclude the various kinds of prepared paper used in manifold writing,some of which are sold under the names carbonic-ink paper and carbon pa-The essential feature of my invention consists of the addition to orcombination with the plate or-board employed to give solidity whenwriting and a rest for the hand of a clip or grip by which one edge ofthe sheet or sheets of carbonic paper may be held, so that the combinedsupporting-plate and carbonicpaper carrier may be handled withoutbringing the fingers into contact with the carbonic paper.

I will describe my invention in connection with the accompanyingdrawings, of which Figure 1 represents in plan the combinedsupporting-plate and carbonic-paper carrier with the sheet of carbonicpaper applied thereto. Fig. 2 is a portion of the same, drawn to alarger scale, without the carbonic paper. Fig. 3 is a section on theline 0 00, Fig. 2; and Fig. 4. is a similar view to Fig. 3, thegripping-bar of the clip or grip in the said Fig. i being in its openedor raised position. Figs. 5 and 6 are perspective views illustrating theuse of the combined supporting-plate and carbonic-paper carrier.

Referring to Figs. 1 to 6, both inclusive, (0 is the supporting plate orboard, having combined therewith (at one side) a clip or grip, thegripping-bar of which is marked 6. c is the sheet of carbonic paper,secured to the plate a by the bar 5. The gripping-bar Z) when in itsclosed or gripping position, Figs. 1, 2, and 3, occupies a shallowtrough (Z near the edge, hereinafter called the outer edge of the platea, the upper surface of the bar I) be ing flush with the surface of theplate a. To increase the effect of the gripping action of the bar 7) onthe sheet of carbonic paper 0, the under surface of the bar 6 and bottomof the trough (Z are corrugated, as is best seen in Figs. 3 and 4:. Thebar 6 is provided, approximately centrally thereof, with a projectionforming a lever g,

which has its upper face slightly below the plane of the upper face ofthe gripping-bar b. The lever 9 extends through an opening in the platea at that side of the trough d which is nearer the outer edge of theplate a, and is connected to the lower face of said plate by means ofaspring-hinge, the joint or hinge-pin of which is denoted by thereference character a and the wire springs thereon by f. A trough-likepiece secured to the lower face of the lever 9 forms a cover for thesprings f and serves to preventdust and other foreign matter fromgaining access to the springs. The outer edge of the plate a has acut-away portion under which extends the free end of the lever 9, sothat when said free end is depressed the bar 6 is caused to rise fromthe trough (Z.

The carbonic paper 0 is applied to the sup porting-plate (o by raisingthe bar bby pressure of the thumb on the lever g and slipping one of thelongitudinal edges of the sheet of carbonic paper 0 under the said bar6. On relaxing the pressure of the thumb on the lever g the bar 7)closes down on the edge of the carbonic paper 0 and grips it in thetrough or depression dwith such tightness as to render its accidentaldetachment from the supporting-plate a practically impossible. WVhen itis desired to introduce the supporting-plate a and carbonic paper 0 intoa manifold-copy book, the plate a is taken by its outer edge in theright hand and by turning the wrist the said plate ais nearly inverted,as is illustrated in Fig. 5. By this action the inner edge of thecarbonic paper is caused to leave the plate,- as is shown by the saidFig. 5. The manifoldcopy book being opened at the desired place, thesupporting-plate a is introduced therein, the last leaf of a set whichare about to be duplicated being allowed to fall or close on the plate.The sheet of carbonic paper 0 is turned onto the leaf on the plate, asis illustrated in Fig. 6, and the leaf or form which is to be writtenand simultaneously copied is permitted to close on the carbonic paper.To withdraw the supporting-plate a and carbonic paper 0, it is onlynecessary to take hold of the outer edge of the plate a and draw thesaid plate outward, when the carbonic paper 0 is simultaneouslywithdrawn.

It is thought that themany advantages of my improved carbon sheet holdercan be readily understood from the foregoing description, taken inconnection with the accompanying drawings, and it will, furthermore, beevident that changes, variations, and modifications can be resorted towithout departing from the spirit of the invention or sacrificing any ofits advantages, and 1 therefore do not wish to restrict myself to thedetails of construction hereinbefore described and as shown in theaccompanying drawings, but reserve the right to make such changes,variations, and modifications as come properly within the scope of theprotection prayed.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A carbon-sheet holder com prising a base member having a trough at apoint removed from one end thereof, an opening at one side of saidtrough, said trough end of the base having its edge cut awayapproximately centrally thereof, a gripping-bar for gripping acarbon-sheet in said trough and having a projection extending throughsaid opening and below the lower face of the base and past said cut-awayportion, and a spring-hinge attached to the lower face of the base andengaging with said projection for connecting the bar to the base andretaining the bar in close contact with the base, said projectionadapted, when its free end is depressed, to cause the grippingbar torise from the trough and thereby release the carbon-sheet from the basemember.

2. A carbon-sheet holder, comprising a base member having a trough at apoint removed from one end thereof, said trough provided withcorrugations, an opening at one side of said trough, said trough end ofthe base having its edge cut away approximately centrally thereof, agripping-bar for gripping a carbonsheet in said trough, saidgripping-bar provided on its lower face with corrugations, saidgripping-bar further provided with a projection extending through saidopening and below the lower face of the base and past said cut-awayportion, and a spring-hinge attached to the lower face of the base andengaging with said projection for connecting the bar to the base andretaining the bar in close contact with the base, said projectionadapted, when its free end is depressed, to cause the grippingbar torise from the trough and thereby release the carbon-sheet from the basemember.

3. A carbon-sheet holder, comprising a base member having a trough at apoint removed from one end thereof, an opening at one side of saidtrough, said trough end of the base haying its edge cut awayapproximately centrally thereof, a gripping-bar for gripping acarbon-sheet in said trough and adapted when in its effective relation,to present its upper face approximately in the same plane with the upperface of the base member, said grippingbar further provided with aprojection extending through said opening belowthe lower face of thebase and past said cut-away portion, and a spring-hinge attached to thelower face of the base and engaging with said projection for connectingthe bar to the base and retaining the bar in close contact with thebase, said projection adapted, when its free end is depressed, to raisethe gripping-bar from the trough and thereby release the carbon-sheetfrom the base member.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

FRED. JEFFERSON.
